qemu-kvm commit: b73357ecd2b14c057134cb71d29447b5b988c516

kvm commit: a72e315c509376bbd1e121219c3ad9f23973923f

After restoring from saved img, some I/O errors appear in dmesg and file
system is read-only.  I'm sure that the  guest runs normally before
saving. See the pictures attached in detail.

Reproduce steps:
----------------
1.create a guest:
  qemu-img create -b /share/xvs/img/app/ia32e_SMP.img -f qcow2 /root/test03=
20.img
  qemu-system-x86_64  -m 256  -net nic,macaddr=3D00:16:3e:06:8a:08,model=3D=
rtl8139 -net tap,script=3D/etc/kvm/qemu-ifup -hda /root/test0320.img
2.save the guest: =

  on qemu monitor: migrate "exec:dd of=3D/root/test-save.img"
3.quit from qemu: =

  "q" command on qemu monitor
4.restore from img just saved:
  qemu-system-x86_64  -m 256  -net nic,macaddr=3D00:16:3e:06:8a:08,model=3D=
rtl8139 -net tap,script=3D/etc/kvm/qemu-ifup -incoming=3D/roo/test-save.img
5.see dmesg in restored guest, you'll find some I/O errors. And run some
commands such as "ps", "touch","reboot" and so on. Then some I/O errors app=
ear.
